摘要:
A bag (1) for microwave heating of food (2) comprises a wall (3) made from a foil (4) that comprises a sealable inside layer (7), and a closure-seal (8) that hermetically seals an inside (9) of the bag (1) from an outside (10) of the bag (1), wherein the closure seal (8) is created by sealing together areas of the inside layer (7), and a valve (11) located inside the bag (1) that separates a first part (13) of the bag (1), which encloses a volume (14) intended to carry the packaged good (2), from a second part (15) of the bag (1), wherein the valve (11) comprises a number of valve-seals (16) that seal together areas of the inside layer (7), and a number of valve-channels (17) that are located between sealed together areas of the inside layer (7).

The package generally includes at least one front and back panel joined at least partially together to define an interior accessible through an access opening. The interior is capable of storing and dispensing product and other objects or materials. Further, at least one web member can be joined to each of the front and back panel portions respectively to form at least two generally parallel chambers and/or channels that extend generally along at least a portion of the access opening. In one embodiment, each of the chambers includes a reservoir or storage portion and a closure portion in fluid communication such that either the reservoir portion or the closure portion are generally inflated or expanded to correspondingly close or open the access opening.

In the pouch manufacturing method of the present invention, a valve member (103) which restricts the movement of the contents when the pouch is formed is conveyed in accordance with the conveying of web-form body members (101,102) that form the pouch, and this valve member (103) is welded to the body members (101,102) in a state in which a sealing preventing member (106) is interposed on the side on which the contents pass through; accordingly, pouches that have a valve function such as a reverse flow preventing function or the like can be continuously manufactured.
摘要:
A packaging bag and a method of manufacturing the packaging bag, the packaging bag formed by heat-sealing plastic films and having an outflow port (3) formed of a heat seal part (2) and a non-heat seal part (6), wherein the inner surfaces of the films forming the non-heat seal part (6) side of a boundary part (Y) between the heat seal part (2) and the non-heat seal part (6) of an outflow port passage (4) come into contact with each other without providing a clearance in closed state, whereby contents can be prevented from oozing out of the outflow port (3); the method comprising the steps of transferring a valve material (103) limiting the movement of filled material after a bag is formed according to the transfer of web-like body materials (101, 102) forming the packaging bag, and heat-fusing the body materials (101, 102) to the valve material (103) in the state of a seal obstructing member (106) provided on the passing side of the filled material, whereby the packaging bag having a valve function such as a reverse flow prevention function can be continuously manufactured.

摘要:
A flexible packaging laminate for a microwavable package (10) has a built-in vent (20) for steam. The vent (20) is formed by an outer score line (33) through the outer layer(s) (32) of the laminate to define an outer flap (36), and a smaller-footprint inner score line (35) formed through the inner layer(s) (34) of the laminate, so that there is a marginal region (AM) of U- or V-shape bounded between the two score lines (33, 35). A patch of pressure-sensitive adhesive (40) is disposed between the outer and inner structures (32, 34) of the laminate such that PSA is present in the marginal region (AM). Pressure exerted on the inner flap or plug (38) created by the inner score line (35) overcomes the PSA between the outer flap (36) and the inner structure (34) in the marginal region (AM), causing the outer flap (36) to be pushed out along with the inner flap or plug (38), thereby venting steam through the resulting opening.
